construction sites.

3 Getting Started
3.1 Battery Tips
Battery life depends on the network, signal strength, temperature, features, and
accessories you use.
Always use Sendum Original batteries and battery chargers. The warranty does
not cover damage caused by non-Sendum batteries and/or chargers.
New batteries or batteries stored for a long time may take more time to charge.
When charging your battery, keep it near room temperature.
When storing your battery, keep it uncharged in a cool, dark, dry place, such as a
refrigerator.
Never expose batteries to temperatures below -10°C (14°F) or above 45°C
(113°F). Always take your device with you when you leave your vehicle.
It is normal for batteries to gradually wear down and require longer charging
times. If you notice a change in your battery life, it is probably time to purchase a
new battery.
Contact your local recycling center for proper battery disposal.
Warning: Never dispose of batteries in a fire because they may explode.
Before using your device, please read the battery safety information in the Safety and
General Information section included in this guide.
